Many of the next generation mobile phones and gadgets are equipped with latest Bluetooth 3.0 technology. And we all have the same belief that it increases Bluetooth speed dramatically. But people are stunned when they see its speed is almost same as Bluetooth 2.0. So what’s the problem? Why is this big speed difference happens?

GSMArena researched the Bluetooth 3.0 issue and the reason for the low speeds. And they find that it’s a simple case of confusing labels. You were getting became instantly clear when you know everything about Bluetooth 3.0.

The Bluetooth 3.0 specifications consists with three things – Unicast connection-less data, Enhanced Power Control and Alternate MAC/PHY.

The Unicast part specifies a way to send a little data without much delay (e.g. a remote control). The Enhanced Power Control keeps a tighter reign on the transmitting power and makes the device a little more power-efficient.

This two features are the good sides of Bluetooth 3.0. Now comes the Alternate MAC/PHY section of the specifications which is much more complicated than others. It’s also the section that’s not mandatory to get a Bluetooth 3.0 certification. It allows two Bluetooth 3.0 certified devices to connect over a Bluetooth link and then switch to a 802.11 link, the base technology for Wi-Fi to achieve speeds of up to 24Mbps.

Devices that support Alternate MAC/PHY are certified as “Bluetooth 3.0+HS” (High Speed) and ones that don’t are certified as just “Bluetooth 3.0” and are limited to regular Bluetooth transfer speeds because of lacking Wi-Fi magic link.

Another important research reveals that Android 2.2 doesn’t even support Bluetooth 3.0 – the BlueZ library that it uses is old and works only up to Bluetooth 2.1+EDR. You can check Bluetooth support info for the other Android versions over at their dev site (there’s no info on Gingerbread though).

It’s possible that manufacturers use a different software stack, but the transfer between the two Bluetooth 3.0 certified Samsung droids we tested was going at v2.1 speeds, so that wasn’t it.

Most importantly none of the present phones they checked were Bluetooth 3.0+HS certified. This put an end to this speed test – 24Mbps just wasn’t going to happen so when you come to pick your next futuristic smartphone. You can safely ignore the Bluetooth 3.0 specs as long as they don’t list HS explicitly. The Bluetooth SIG website settled any remaining doubts you had.Source

Charging your mobile phone is always na periodic boring task. This task goes even worse when you have many different phones from different manufacturers. You must carry all the necessary chargers along with the phone wherever you go. But the scenario will change soon. The European Union first announced the plan of using same charger port on every handset in last year June. According to the plan every mobile phone manufacturers must use same charger port from coming 2011. And this common charger port is micro usb which are already used in many handsets.

All the major phone manufacturers like Nokia, Apple, Samsung, LG, RIM, Sony Ericsson, Motorola, Huawei, Alcatel, NEC, Emblaze, and chip makers Qualcomm, Texas Instruments and Atmel quickly signed the memorandum. A few others signed later on. So you don’t need to worry about your next phone.

Convenience is one thing to look forward to. No more carrying several chargers for each device - just one will do. You can even use a microUSB cable and a computer to charge your mobile phone. The switch to the microUSB standard has environmental benefits as well, as each year 4,000 tons of old, incompatible accessories get thrown out after the user upgrades.

The first phones complying with the new standard are expected to come out early next year in Europe anyway. But everyone hoping that the phone makers will use the standard globally rather than create Europe-specific versions with microUSB.Source

Dual-core Tegra2 Processor based LG Optimus 2X will hit European market in January 2011 with a price tag of €550. A Swedish website publish this price and start taking preorders for this exclusive LG Android 2.2 Froyo smart phone.
And if you wish to buy one of those then you will get something special inside- a famous Italian composer will share part his movie soundtracks as 15 LG exclusive ring tones with the future owners of the LG Optimus 2X(also known as LG P990 Star). Among the 25 pieces composed by Morricone there will also be 10 of the composer's creations such as tracks from the movies Cinema Paradiso, The Mission, Love Affair. What's more Optimus 2X users will get access to free applications with Ennio Morricone images and video clips from the LG Application Store.

Its now almost certain that LG Optimus 2X has the best mobile phone display ever produced inside, even better that IPS Retina based iPhone 4 and Super AMOLED Samsung galaxy S. The TFT capacitive 480 x 800 pixels 16M color touchscreen seems brighter and more energy efficient. And the android LG beast also expected to be thinner than Apple iPhone 4 and Samsung Galaxy S, may be just 9.3 mm.
ARM Cortex A9 1GHz dual-core processor used in this LG optimus 2X. And Android 2.2 Froyo is also upgradable to Android 2.3 gingerbread. LG Optimus 2X has 8 GB of internal memory, 32 GB of memory card support, 3G HSDPA support, Wi-Fi 802.11 b/g/n. And its 8 megapixel camera is capable of taking 1080p HD video. And as usual 720p tv out and HDMI port also here.

2011 might be the year of display fight among the mobile phone manufacturers. Both mobile display size and quality are head to head on this fight. Apple mainly fires the race with it’s iPhone 4 IPS super bright display. And last November 2010 Acer has announced one of the most appealing Android smartphones of the season. With a 4.8 inches 16M TFT capacitive touchscreens with six-axis gyro sensor, new Acer android phone has the highest resolution display in the Android market todays. After a month of official announcement the name of this handset is still unknown.
The android 2.2 Froyo device comes with a huge 4.8-inch display with a resolution of 1024 x 480 pixels, that's a pretty wide 2.13:1 aspect ratio. This android phone has a 8 megapixel 720p HD video recording capable camera with autofocus, LED flash and image stabilization. And front facing camera is also 2 megapixel. That’s good for the video chat lovers.

Dual-SIM is an important features still now lacking in modern smart phones. But at last we see the lights end of the tunnels for Dual-SIM high performance sets. Gigabyte is preparing to launch a dual-SIM smartphone running on Android 2.2 Froyo. It’s called GSmart Rola G1317 and it will launch in early 2011. And price of this mid-end Andoird 2.2 Dual-SIM phone is set to $214.You might be missing a point that Gigabyte already running Windows Mobile 6.5 on another Dual-SIM phone GSmart 1205 very successfully. But the price of Dual-SIM Windows Mobile phone is too high for the average users- $1205. Now Gigabyte is ready to take their dual-SIM business over at the Android camp. The GSmart Rola runs Android 2.2 Froyo but packs with barely decent features – a 3.2-inch resistive WQVGA 240 x 400 pixels touchscreen, equipped with 528MHz processor, 256MB RAM, 512MB ROM, 3 mega pixel fixed-focus camera and a microSD memory card slot.

But you feel very confident with dual sim Rola’s connectivity. Gigabyte GSmart Rola has everything covered – Wi-Fi, quad-band GSM, GPRS, EDGE, 3G with HSDPA support, GPS with aGPS support and digital compass, Bluetooth 2.1 and Stereo FM radio. But there is still question over dual sim 3G support- whether it is available in one or two SIM. But we assume that 3G would be available only on one of the SIMs though.Source
